T0 aZZ whom it m0ty eoncern:

Be it known that I, JOSEPH J. KULAGE, of

St. Louis, Missouri, have made a new and use fu1 Improvement in Brick-Machines, of which the following is a full, clear, and exact de scription.

The present improved machine is a coxnparatively simple, compact, and powerful brck-press designed more especially for the pressing int0 bricks of dry and partially dry clay, and particularly those clays which are ure of the machine is brought 0 bear upon the clay er bricks in the meld and then maintained thereo n fora prolonged period,substantially as is hereinafter described and claimed,

aided by the annexed drawings, making part of this specification, in which- Fi gure 1 is a side elevation Of the improved machine; Fig. 2 a side elevation of the camshafts and cams; Fig. 3 a secton on the line 3-3 of Fig. 2; Fig. 4 a vertica], transverse section of the machine on the'line 4-4 of Fig. 1; and. Fig. 5a vertical, longitudinai section 011 the line 55 of Fig. 4.

The same letters of reference denote the same parts.

On1y those portions of the construction whch are essentialto an understanding of its improved features are exhibited in the drawings.

The present machine belongs to that class of brick-machines in which upper and lower plungers are used.

The mold er molds are represented at A, and. B represents the lower plunger, and 0 the upper plunger.

D represents a shaft, journaled in bearings d, d, in the frame-vork, E, of the machine, and provided with three cams, namely a central cam, F, which actuates the upper plunger, and two cams G, G, at the sides respectively, of the central cam, which actuate the lower piunger. In the revolution of the cam-shaft, D,the cam F acts to raise, and also to depress the upper plunger 0, and the other cams, G, G, serve only te lift the lower plunger B.

T0 this end the upper piunger is attahed to a slottedhead, C, in the slot, 0, of whichthe cam F works, thecamn its rotation hearing alternate1y upon some part of the head to raise it, and. then up0n some other part of the head t0 depress it. Said partspreferably take the form of fricton-rollers, c, 0 extending across the slot cand journaled in the head C at the sides respectively of the slot, and substantially as shown. The motion of the other cams, G, G, is communicated to the lower plunger as follows: The lower plunger is attached to, or forms partofa cross-head,B', which, by means of rods H, H, is connected with an upper crosshead, I, having the friction-rollers i, 2. The cams G, G', in their rotation encounter and lower plungers are therby raised. When the cams, G, G, have passed the rollers i,i, the

lower plunger,and the parts connected therewithas described, fall. Any ether sitable means forcommunicating the motion of the cams G, G to the lower plunger, forthe purpose described, can be empioyed.

Motion is imparted to the cam-shaft preferabl y as follws: The cam shaft is provided with agear wheel J, which engages with a pni0n K on a shaft 7a, This last named shaft is journaled in bearings la, la, and it is provided aiso with agear wh'eel, k which en gages with -a pnion, L, upon the diiving shaft Z having.the fast and. loose pulleys, l, 2 The motion of the cam shaft and camsis indicated by the arrow zo, Fig. 5. The shape and arrangement of the cams is a leading feature of the construction. The cam, F, considered generally, is Of a quadran'cal shape, but, more particularly described, as follows: Commencing at the point f, at the inner end of its face, f the cam extends in a semi-circu1ar form to the point f -the cam then curves farther around, but gradually enlarges until the point,f is reached: this last named point is at the throw of the cam; from this point the cam curves around with the same radius, through an are of about ninety degrees, to meet the face of the cam. The throw of the cam is suited to the desired stroke of the upper plunger, and the length of the are, f,0f the camis proportioned to the length of the period during which the pressure is to he tial direetion until the point g is reaehed,-

from this last; named point the backs of the can1s extend in a oircular are, g, until the face of the cam is reached; the relative position of the cam F and the cams G, G, is substantially indica;ted in Figs. 2, 3, and 5.

The operation is asfollows: In Fgs. 4 and 5 the positionofthe parts is as when both of the -plungers have been raised te the upper 1imitsof their respeeiqive strokes, and. the recharging of the molds is about: to be accomplished: the cams G, G, now passthe rollers i, 2, and the 1ower piunger in eonsequence falls to the bott0m of the molds,making room ferthe new charge: the upper plungel: must;

be upheid until the charging of the molds is effected: this is aecomplshed;- by means of the portion, f, of the cam F, the upper plunget being npheld until the face, f', 0f that can1 passes the roller 0; the upper piunger is now no longer upheld and itdr0ps untii it rests upon the. contents -of the molds: i'lt 01- about this peint of time 'chepoinbf of -'che cam F has come to a beaming upon the lowerfrictien-rollen 0 and the pressure upon the contents of the rnoids has; been inirieteci:- the pressure continues toinerease until thepointf of the cam eomes t0 beer upon the roller 6 the maximum pressure of the pressis now obtained,and such maximum pressure is retained upon the contents of the molds nnt1 the portion f of the cam has passed the roller 0 whereupon,in the rotation of the cam shafts and cams, the operation is repeated.

The mechanism f0i operating the charger, M, being well understood, is not illustrated. The fa1l ef the 1ower plunger in the molds is reguiated preferably by means of the wedge N. The wedge engages with the horizontally amanged, threaded stem n, which is held and adapted to rotate in a bearingn', in the framework E. The lower ciosshead is beveled at 1), to coach With the wedge.

In carrying out this improvement I desire net te be restricted t0 biiekmachines, as a prees. eontaining the improvement is adaptab1e f0r compressng various substances into vai ious forms, and fonvarious PHIPOBOS. The imp1oved machine is desirable f0i its simplieity, eompaetnessand strength. 'Iheeams are all on one shafn: thepressure isobtained without the use of toggles or levens: a single shaft suffices for operating both lowen and upper plungers: the ca.ms can be integral with the shaft; the pressure can be inain tained upon the contents of the molds aslong as desred the camshafb and eamsare above the moid-table and thus out of the way 1argeiy
